By connecting this DB-9 port, it allows you to configure & check the status of
Managed Switch even when the network is down.
IP Addresses
IP addresses have the format n.n.n.n, (The default factory setting is 192.168.0.1).
IP addresses are made up of two parts:
The first part (for example 192.168.n.n) refers to network address that identifies the
network in which the device resides. Network addresses are assigned by three
allocation organizations. Depending on your location, each allocation organization
assigns a globally unique network number to each network that wishes to connect to
the Internet.
The second part (for example n.n.0.1) identifies the device within the network.
Assigning unique device numbers is your responsibility. If you are unsure of the IP
addresses allocated to you, consult with the allocation organization where your IP
addresses were obtained.
Remember that none of the two devices on a network can have the same address. If you
connect to the outside network, you must change all the arbitrary IP addresses to comply
with those you have been allocated by the allocation organization. If you do not do this, your
outside communications will not be performed.
A subnet mask is a filtering system for IP addresses. It allows you to further subdivide your
network. You must use the proper subnet mask for proper operation of a network with
subnets defined.
MIB for Network Management Systems
Private MIB (Management Information Bases) is provided for managing the Managed switch
through the SNMP-based network management system. You must install the private MIB
into your SNMP-based network management system first.
The MIB file is shipped together with the Managed Switch. The file name extension is “.mib”
that allows SNMP-based compiler can read and compile.
